Hi all

I want to build an Applet that use Robot Class to capture screen :
Robot myRobot = new Robot(myGraphicsDevice);

the problem is that the Java output panel show this message:
java.security.AccessControlException: access denied (java.awt.AWTPermission
createRobot)
at java.security.AccessControlContext.checkPermission(Unknown Source)

Can anyone tell my the reason of this exception ????

best regard,
max

Yep, you'll have to sign your applet.

What do you mind about "sign your applet" ?
I must use a software to sign an applet or automatic process ?
